PHP file Removal unlink () detailed _php tutorial

Deleting files in PHP is simple as long as you use the Unlink function to complete the deletion, if you want to delete all the files in the directory we need to use the recursive operation directory to delete.

Remember the lesson created from PHP files, we created a file named TestFile.txt.

The code is as follows	Copy Code
$myFile = "TestFile.txt"; $fh = fopen ($myFile, ' w ') or Die ("can ' t open file"); Fclose ($FH); Determine if it was deleted. $myFile = "TestFile.txt"; Unlink ($myFile);

Cases

The code is as follows	Copy Code
$filename = ' file.txt '; fopen ($filename, ' A + '); if (!unlink ($filename)) { echo "File {$filename} delete failed"; } Else { echo "File {$filename} deleted successfully"; } ?>

Delete all files under directory

The code is as follows	Copy Code
function Delfileunderdir ($dirName = ": /smarty/templates/templates_c ") { if ($handle = Opendir ("$dirName")) { while (false!== ($item = Readdir ($handle))) { if ($item! = "." && $item! = "...") { if (Is_dir ("$dirName/$item")) { Delfileunderdir ("$dirName/$item"); } else { if (unlink ("$dirName/$item")) echo "successfully deleted file: $dirName/$item n "; } } } Closedir ($handle); } }
